In this video, we will learn how to measure distance with an HC-SR04 ultrasonic range finder connected to an Arduino. Temperature and humidity can affect the accuracy, but there's an easy way to compensate for it.
This is tutorial #34 in the Ultimate Guide to the Arduino, a complete video course on the Arduino microcontroller with 45 lessons that are designed to teach anyone how to master the Arduino at any skill level. Visit our KZfaq channel page to watch the entire series!
